slightly emarginate, acute-angled lamina, in the female broadly 

 rounded and reflexed. Thorax black, sharply punctate, and 

 glabrous except on the lateral margins, with the median line 

 marked tbroughcut. Elytra reddish-brown, glabrous, and strongly 

 and irregularly striate-punctate. Body beneath black, the two last 

 segments large, red, glabrous and punctate. The four anterior legs 

 piceous-red, the anterior tibiae tridentate. 



Length, 3 lines.

Smaller than L. ferrugineus, but of the same form. Entirely 

 black excepting the two last segments of the abdomen and the 

 anterior legs which are piceous, glabrous and nitid above and 

 cinereo-villose beneath. The clypeus of the male is less promi- 

 nently laminated than in L . ferrugineus, the thorax has no median 

 line, and the elytra are rather more rugosely striate-punctate. The 

 anterior tibiae are strongly tridentate. 



Length, 2J lines.

85. Liparetrus basalis, Blanch. 



Cat. Col. Mus. Paris, p. 105. 



Ovate, black, above nigro-pilose, beneath cinereo-villose. Head 

 rugosely punctate, the clypeus reflexed and three-sided. Thorax 

 rugosely punctate, pilose, the median line impressed. Elytra 

 brownish-red, the base blackish, rugosely punctate in irregular 

 striae. Pygidium rugosely punctate and villose. Anterior tibiae

This species has two characters which are to be found in most 

 of the following species and which is never found in any of the 

 9-jointed antennae group ; (1) the form of the clypeus presenting 

 three more or less truncate faces, and (2) the anterior tibiae having 

 two approximate teeth on the outer apex, and with generally 

 another near the base.
